Climbing rose plant named ‘BAIPEACESAR’

ABSTRACT

A new and distinct Climbing rose plant is provided that forms on a substantially continuous basis attractive blossoms having a blend of yellow and carmine pink coloration. The vegetation is dense dark green and very strong, and bears a glossy aspect on the upper surface. The plant has been found to grow well on its own roots. No particular disease problem has been observed during observations to date. The plant is particularly well suited for providing attractive ornamentation in parks and gardens.

Botanical/commercial classification: Rosa hybrida/Climbing Rose Plant.

Varietal denomination: cv. Baipeacesar.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Climbing rose plant was discovered in France during 2013 as a spontaneous mutation of unknown causation of the ‘Baipeace’ variety (U.S. Plant Pat. No. 14,731, granted Apr. 27, 2004). The discovery was made primarily in view of the distinctive climbing growth habit that was displayed in a plant nursery setting tended by man. Had the new plant not been discovered and preserved it would have been lost to mankind.

It was found that the new rose plant of the present invention:

-   -   (a) displays a climbing growth habit with very strong         vegetation,     -   (b) forms in abundance on a substantially continuous basis         attractive double blossoms exhibiting a blend of yellow and         carmine pink coloration,     -   (c) grows well on its own roots,     -   (d) exhibits attractive dense dark green foliage with a glossy         aspect on the upper surface, and     -   (e) is particularly well suited for providing attractive         distinctive ornamentation in parks and gardens.

The blooming tends to commence early in the season during observations to date. The blossoms coloration contrasts nicely with that of the dark green foliage.

The new variety well meets the needs of the horticultural industry and can be grown to advantage where attractive ornamentation is to be provided.

The new variety can be readily distinguished from its ‘Baipeace’ parent in view of the dissimilar growth habit. More specifically, the ‘Baipeace’ variety displays an unlike upright growth habit.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques at Le Cannet des Maures, Var, France, has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner. The plant grows well on its own roots.

The new variety has been named ‘Baipeacesar’.

The rose plants of the new variety were approximately one year of age and were observed during June while growing outdoors on their own roots at Le Cannet des Maures, Var, France. Comparative standard color information is included at the base of the photograph.

The new ‘Baipeacesar’ variety             has not been observed under all possible environmental             conditions to date. Accordingly, it is possible that the             phenotypic expression may vary somewhat with changes in             light intensity and duration, cultural practices, and other             environmental conditions. 

I claim:
 1. A new and distinct rose plant characterized by the following characteristics: (a) displays a climbing growth habit with very strong vegetation, (b) forms in abundance on a substantially continuous basis attractive double blossoms exhibiting a blend of yellow and carmine pink coloration, (c) grows well on its own roots, (d) exhibits attractive very dense dark green foliage with a glossy aspect on the upper surface, and (e) is particularly well suited for providing attractive distinctive ornamentation in parks and gardens; substantially as shown and described.
